Explanation

First, arrange the numbers in order of magnitude:-6,1,2,3,5,20,21,25,28,30,32,34hence, range = 34 -(-6)= 34+6=40To find the range of a set of numbers, you subtract the smallest number from the largest number in the set.Given the set of numbers: 20, -6, 25, 30, 21, 28, 32, 33, 34, 5, 3, 2, and 1The smallest number is -6 and the largest number is 34.So, the range is:34 - (-6) = 34 + 6 = 40Therefore, the range of the given set of numbers is 40.
